Taking vitamin supplements may no longer be a mantra to stay fit. New research suggests that certain vitamins can have adverse effects on human lifespan.
Researchers at the University of Copenhagen reviewed more than 815 clinical trials into the benefits of commonly used vitamin supplements, including vitamins A, E and C besides beta-carotene and selenium.
They found that vitamin supplements appeared to raise, not lower, the risk of early death, reported online edition of BBC News.
Millions worldwide use antioxidant supplements, including vitamins A and E, believing it improves health. Nutritionists suggest a balanced diet instead.
Food contains a complex matrix of different components, which could not be replicated by supplements, British Dietetic Association nutritionist Frankie Phillips said.
"Our advice is to eat a wide range of foods in a balanced diet that can provide all of the nutrients the body needs to protect itself and combat diseases."
